[0018] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the description of the textual part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0019] Reference Figure 1-6 The present invention provides an online continuity testing device for a new energy battery harness assembly line, comprising: a workbench 1, a continuity testing body 2 and a fixing plate 3 fixedly mounted on the upper surface of the workbench 1, a testing port 7 and a dustproof component 5 provided on the outer wall of the fixing plate 3, a driving component 6 provided on the inner wall of the workbench 1, and a harness port fixing component 4 provided on the driving component 6. The wire harness port fixing assembly 4 includes a base 41 and an upper pressure block 42. The upper surface of the base 41 and the lower surface of the upper pressure block 42 are provided with port fixing grooves 49 and wire harness fixing grooves 410, respectively. A guide rod 43 is fixedly installed at one end of the upper surface of the base 41. A turntable groove 44 is provided at one end of the base 41. A turntable 45 is rotatably installed on the inner wall of the turntable groove 44. A drive threaded rod 46 is fixedly installed on the outer wall of the turntable 45. The drive threaded rod 46 passes through a through hole opened on the upper surface of the base 41. A guide groove 47 is provided at one end of the upper pressure block 42. An internal threaded groove 48 is provided at the other end of the upper pressure block 42. The drive threaded rod 46 is threadedly connected to the inner wall of the internal threaded groove 48. The guide rod 43 is slidably installed on the inner wall of the guide groove 47.

[0020] In the online continuity testing device for new energy battery harness assembly line described in this utility model, the port portion of the harness is embedded in the port fixing groove 49 on the upper surface of the base 41, and the cable portion is embedded in the harness fixing groove 410 for initial positioning. The operator rotates the turntable 45 in the turntable groove 44, which drives the fixed drive threaded rod 46 to rotate. Since the drive threaded rod 46 is threadedly connected to the internal thread groove 48 of the upper pressure block 42, and the guide groove 47 of the upper pressure block 42 slides along the guide rod 43 of the base 41, the guide rod 43 can restrict the rotation of the upper pressure block 42. The rotation of the drive threaded rod 46 will be converted into the downward movement of the upper pressure block 42 until it fits against the base 41. The harness port and cable are firmly clamped by the cooperation of the upper and lower corresponding grooves to avoid loosening during testing and poor contact.

[0021] The drive assembly 6 includes a forward and reverse motor 61 and a drive rod 64. The forward and reverse motor 61 is fixedly installed on the inner wall of the worktable 1. A first bevel gear 62 is fixedly installed on the output shaft of the forward and reverse motor 61. A second bevel gear 63 is fixedly installed on the outer wall of the drive rod 64. The second bevel gear 63 and the first bevel gear 62 are meshed together. A first threaded rod 65 is fixedly installed on one end of the drive rod 64, and a second threaded rod 66 is fixedly installed on the other end of the drive rod 64. An internal threaded ring 67 is threaded onto the outer wall of the first threaded rod 65 and the second threaded rod 66. A connecting rod 68 is fixedly installed on the outer wall of the internal threaded ring 67. The top end of the connecting rod 68 is fixedly installed on the lower surface of the base 41. The first threaded rod 65 and the second threaded rod 66 are rotatably installed on both sides of the inner wall of the worktable 1 through a mounting bracket. A first stroke groove is opened on the upper surface of the worktable 1. The connecting rod 68 is slidably connected to the inner wall of the first stroke groove.

[0022] In the online continuity testing device for new energy battery harness assembly line described in this utility model, the forward and reverse motor 61 fixed to the inner wall of the workbench 1 is started, and its output shaft drives the first bevel gear 62 to rotate. The first bevel gear 62 meshes with the second bevel gear 63 on the drive rod 64, thereby driving the drive rod 64 to rotate, so that the first threaded rod 65 at one end of the drive rod 64 and the second threaded rod 66 at the other end rotate synchronously. Since the outer walls of the first threaded rod 65 and the second threaded rod 66 are threaded with internal threaded rings 67, and the internal threaded rings 67 are connected to the lower surface of the base 41 through the connecting rod 68, and the connecting rod 68 slides in the first stroke groove opened on the upper surface of the workbench 1, under the action of the threads, the internal threaded rings 67 rotate. 67 will drive the connecting rod 68 to move along the first stroke groove, thereby driving the wire harness port fixing assembly 4, which has the wire harness fixed, to move towards the fixing plate 3, so that the wire harness port is accurately connected to the detection socket 7. At this time, the detection body 2 establishes an electrical connection with the wire harness port through the detection socket 7, and starts the detection program. By applying a specific electrical signal, it detects whether there are faults such as open circuit, short circuit, and poor contact in the wire harness, and records and feeds back the results. After the detection is completed, the forward and reverse motor 61 reverses, driving the first threaded rod 65 and the second threaded rod 66 to rotate in the opposite direction, so that the internal threaded ring 67 and the connecting rod 68 drive the wire harness port fixing assembly 4 to reset. The operator rotates the turntable 45 in the opposite direction to move the upper pressure block 42 up to release the wire harness and remove the tested wire harness.

[0023] The dustproof component 5 includes a dustproof plate 51 and a pull block 56. A slider 52 is fixedly installed on the outer wall of the dustproof plate 51. A first insertion hole 53 and a second insertion hole 54 are opened on both sides of the dustproof plate 51. A pin 55 is fixedly installed on one end of the pull block 56. A connecting rod 57 is fixedly installed on the other end of the pull block 56. A spring pressure plate 58 is fixedly installed on the other end of the connecting rod 57. A spring 59 is fixedly installed on the outer wall of the spring pressure plate 58. A spring compartment is opened on the fixed plate 3. The other end of the spring 59 is fixedly installed on the inner wall of the spring compartment. A second stroke groove and a sliding groove 510 are opened on the outer wall of the fixed plate 3. The connecting rod 57 is slidably connected to the inner wall of the second stroke groove. The inner wall of the sliding groove 510 is slidably connected to the slider 52.

[0024] In the online continuity testing device for new energy battery harness assembly line described in this utility model, the operator pulls the pull block 56, which drives the spring pressure plate 58 to compress the spring 59 through the connecting rod 57. At the same time, the connecting rod 57 slides in the second stroke groove of the fixed plate 3, and the pin 55 is pulled out from the first insertion hole 53 of the dustproof plate 51. Then, the dustproof plate 51 is pushed so that the slider 52 on its outer wall slides in the sliding groove 510 of the fixed plate 3, exposing the detection insertion port 7. After that, the pull block 56 is released, the spring 59 returns to its original position, and drives the spring pressure plate 58, the connecting rod 57 and the pull block 56 to move back. The pin 55 is inserted into the second insertion hole 54 to complete the fixation.

[0025] Working principle: First, pull the pull block 56 horizontally. The pull block 56 moves the pin 55 out of the first socket 53. Simultaneously, the pull block 56 moves the spring pressure plate 58 through the connecting rod 57, causing the spring pressure plate 58 to press the spring 59, forming a compressed state. Then, push the dustproof plate 51 upward to expose the detection socket 7. When the second socket 54 and the pin 55 are on the same horizontal line, the pull block 56 can be released. The elastic force generated by the compression of the spring 59 drives the pin 55 to reset, allowing the pin 55 to insert into the second socket 54, thus fixing the dustproof plate 51 again. Then, rotate the turntable 45, which drives the drive threaded rod 46 to rotate. The drive threaded rod 46 is threadedly connected to the inner wall of the internal thread groove 48 on the upper pressure block 42. When the drive threaded rod 46 rotates, it drives the upper pressure block 42 to move upward, exposing the port fixing groove 49 and the wire harness fixing groove 410 on the base 41. Then, place both ends of the wire harness... The wire harness is placed on the port fixing slot 49 and wire harness fixing slot 410 on the base 41. Then, the turntable 45 is rotated in the opposite direction to reset the upper pressure block 42, thereby fixing both ends of the wire harness. Then, the forward and reverse motor 61 is started. The output shaft of the forward and reverse motor 61 drives the first bevel gear 62 to rotate. The first bevel gear 62 and the second bevel gear 63 are meshed and connected. The rotation of the first bevel gear 62 drives the rotation of the second bevel gear 63. The rotation of the second bevel gear 63 drives the drive rod 64 to rotate. The drive rod 64 synchronously drives the first threaded rod 65 and the second threaded rod 66 to rotate. The internal threaded ring 67, which is threaded on the outer wall of the first threaded rod 65 and the second threaded rod 66, is displaced while the first threaded rod 65 and the second threaded rod 66 are rotating. While the internal threaded ring 67 is displaced, it drives the base 41 to move through the connecting rod 68, moving both ends of the wire harness to the detection socket 7, so that the ends of the wire harness are inserted into the detection socket 7 for continuity testing.

[0026] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
